Soy products : Good or bad? (Pt.2) 🔴"But soy contains estrogen which causes breast cancer!!" Soy contains phytoestrogen, which is a plant-derived estrogen that is similar in composition with human estrogen but is not scientifically related or affects the human body the way estrogen does since estrogen and testosterone are sex hormones. Phytoestrogen are existent in many other plant-based food groups, in grains such as white rice, brown rice, and barley ;
Legumes including lentils ; Seeds including flaxseed, sesame seeds, coffee beans, and fruits and vegetables such as pomegranate, apples, and carrots. Phytoestrogens, specifically "Isoflavones" react with estrogen receptors that are present in the human body but there is not even one scientific evidence proving that phytoestrogens had estrogenic effects on humans, there is not even one situation in which there was an increase in the size of the tumor in a cancer patient or an increased risk of breast cancer in a female patient. But it was proven that it had a positive effect against hormonal diseases. Also consuming non-genetically modified soy products was confirmed to decrease the risk of developing breast cancer, especially when it comes to East Asian countries (Japan, China, Taiwan, South Korea) where populations consume soy products almost every day and happen to have the lowest breast cancer rates in the world. Furthermore, what's being said that Isoflavones cause a decrease in testosterone levels and that they lead to gynecomastia or impotence in men is only mythical, according to latest studies. Some children can't tolerate cows' milk (due to lactose intolerance), so they are prescribed a soy protein formula instead from infancy until 12 months of age and up, some other children are raised on soy formula during their whole childhood. A study from Italy done in 2004 on 48 children (27 males, 21 females) ages from 7 up to 97 months, who had consumed soy formula, didn't prove any abnormality related to hormonal effects whether if there are signs of precocious puberty, gynecomastia, or changes in bone development on the long run in children.
